Our laboratories offer excellent working conditions and are equipped with the-state-of-the art equipment and instrumentation. Here follows more information on the specific instruments used for the various types of analysis and characterization.
Deposition of materials from the vapour phase allows variation of their structural and chemical properties, allowing the production of materials with novel optical properties.
Our facility is centred around a Mantis Deposition Ltd. Molecular Beam Epitaxy (MBE) system, which has Knudsen sources for deposition of II-VI semiconductors, e-beam sources for the addition of transition metal dopants, and atom sources for supplying gas dopants without the disruptive effect of ion bombardment. Additional vacuum systems permit thermal evaporation, ion-assisted deposition, sputtering and Matrix-Assisted Pulsed Laser Evaporation (MAPLE).
Four specialized laboratories at the University of Oslo (UiO) are equipped to pursue a wide set of state-of-the-art techniques to study the dynamics and structure of flow in two- and three-dimensional porous media.
We have a full range of high-resolution and high-speed imaging techniques, including two ultrafast Photron Ultima (SA5 and APX) cameras with 7000 fps at a spatial resolution FLIR SC300 infrared camera used for real-time measurements of heat dissipation in fractures, hydro-fractures and porous media flows and a wide variety of DSLR camera and accompanying optics. Microscale experiments can be imaged via far field microscopy using a Zeiss Stemi 2000-C distorsion-free stereo microscope which couples to our high-speed and high-resolution cameras and is in process of being upgraded for enhanced magnification.

Flicker-free illumination sources tailored for the different applications (including high-speed microscopy) are also available.
We have also recently bought a Krüss DSA25 drop shape analyzer to perform direct measurements of surface tension, wetting properties and surface free energy.
Additionally, our laboratories include a large set of different optical equipment, such as lasers with different intensities and wavelengths, lenses and other optical components, cameras and microscopes for Particle Image Velocimetry.
We are also well-equipped to perform homodyne correlation spectroscopy for the measurement of particle velocity fluctuations in fluids, diffusion constants and viscosities.
In addition to this wide variety of state-of-art techniques, our laboratories are also fully equipped with standard fluid mechanics labware, such as capillary viscometers, high-precision scales, pressure and temperature sensors, surface treatment chemicals for the control of wetting properties and general laboratories glassware.

The core analysis laboratory is equipped with state-of-the-art equipment spanning from automated centrifuge for capillary pressure and relative permeability measurements to core holders, pumps, pressure sensors, flow meters, glass micro models, syringe pumps, microscopes and ordinary digital cameras. The laboratory includes as well some interfacial tension apparatus (pendant drop and spinning drop), contact angle apparatus and viscosity apparatus (Anton Paar rheometer, Brookfield viscosimeter).
We have also the possibility to perform experiments in specialized core flooding rigs and micro CT- micro- flooding rigs.
A description of the main equipment is given here.
